Researchers have described a new species of mountain horned dragon from the high-elevation forests of western Thailand, naming it Acanthosaura syrax after Syrax, the dragon ridden by Rhaenyra Targaryen in HBO's "House of the Dragon."
The lizard was collected from evergreen forest above 1,300 meters in Mae Wong National Park, spanning Thailand's Tak and Kamphaeng Phet provinces, by a team led by Poramad Trivalairat with colleagues from Chulabhorn Royal Academy and Kasetsart University. Their formal description, published in the open-access journal ZooKeys on July 31, brings the number of known species in the genus Acanthosaura — lizards known as mountain horned dragons, or "pricklenapes," for the spiny crest running down their neck and back — to 23.
Why Syrax
The naming wasn't arbitrary. According to the team's account on Pensoft's research blog, researchers chose Syrax deliberately for three traits the fictional dragon shares with the real lizard: striking yellow coloring, a comparatively modest size next to other dragons in its group, and an unusually large number of eggs for its body size. The living Acanthosaura syrax shows yellow-green tones on males' lips and neck, lacks the black eye patch found on related species, and carries the smallest crest scales documented anywhere in the genus.
The species appears to exist nowhere outside its small patch of high-elevation forest, a pattern common among reptiles restricted to isolated mountain habitats across Southeast Asia. EurekAlert's release on the discovery notes that researchers are pushing to use the newly named lizard as a flagship species for stronger protection of Mae Wong's upper forests, alongside better-known residents like the Asian forest tortoise, Oldham's leaf turtle and the Indochinese tiger.
Naming new species after pop-culture figures has become an increasingly common tool for taxonomists looking to draw public attention to conservation-relevant discoveries — recent years have produced species named for characters from "The Lord of the Rings," Pokémon and "Rick and Morty." For Acanthosaura syrax, the description doubles as a quiet case for habitat protection: without secured status for Mae Wong's upper forests, researchers warn, the lizard's entire known range could be lost before it is fully studied.
